StarUML is one of the programs that was created to provide all the necessary components and functions for creating and editing projects that support the Unified Modeling Language (UML) standards and, consequently, are compatible with the Model-Driven Architecture (MDA) specifications.

After being abandoned for some time, the project had a revival to move from Delphi to Java/Eclipse and then stopped again. In 2014, a rewritten version was released as proprietary software. However, the open-source version’s community is still active and Many topics are discussed on the forums.

Conclusion

StarUML has many powerful features and is certainly more than a “simple” diagramming tool. With its support of MDA (Model Driven Architecture), it is more aimed at people using UML in an intensive way and with some code generation objectives than simply drawing diagrams to document requirements. However, using StarUML just as a diagramming tool works fine, especially on Windows as the tool is built with Delphi and might execute faster than the Java-based tools.
